Abstract

In this paper, we studied the radiated electric field of power-line with DMT signal source in the frequency range of $1.7{\sim}30 MHz$. First, we made the midium voltage power-line communication model for PLC and calculated the current through the power-line using the impedance of the power-line model. Second, we calculated the radiated electric field in power range $-50{\sim}-30 dBm$ using the calculated current. Consequently, the calculated emissive electromagnetic field from the DMT signal is similar to the measured result. So this study is applicable to the standard regulation of electromagnetic interference for PLC.
